AbstractThe present invention discloses a treatment process for printing and dyeing wastewater. According to the treatment process, a photoion catalyst is uniformly dispersed in printing and dyeing wastewater under stirring or aeration effect, and vacuum ultraviolet lamp with a light wavelength of 185 nm is adopted as a photocatalytic light source to carry out photoion catalytic degradation on pollutants in the printing and dyeing wastewater to obtain the treated printing and dyeing wastewater; the photoion catalyst can be reused after treating and separating. With the process of the present invention, soluble organisms and insoluble organisms can be degraded, organic pollutants can be degraded, advantages of high decoloration efficiency, complete degradation of the organic pollutants, simpleness and rapidness, no sludge generation, stable operation, low influence due to water quality change, reuse of effluent, and the like are provided, and the process can be widely used in various printing and dyeing wastewater treatments.
